The technique that allows to read the Herculaneum papyri, charred during 79 AD Vesuvius eruption and never read due to their critical state of conservation, is X-ray phase contrast tomography (XPCT). This technique amplifies the contrast between the carbon-based ink used to write on the scrolls and its papyrus support. Thank to the new software, still in the optimization phase, we are able to make a virtual unrolling of the papyrus sheet and read the text completely and non-invasively. We also developed a new method for nondestructive characterization of fragment of the unrolled scroll by using multiple-energies XPCT.
